Q:What is the difference between a variable hob and a non - variable hob?

The design modulus of the shift gear hob is different from the product modulus!

Q:What are the main causes of hob breaking?

The workpiece material hardness is high, the tool is not installed properly

Q:Conjugate gears have different displacement coefficients, so can hobs be used in general?

If the basic parameters of the gear are the same (m * ha * C *), and the tip of the tooth has no trimming, the hob can be used in general. When the addendum of the gear tooth is required, it should be analyzed. If the coefficient of variation between the two coefficients is not large, and the margin of repair is not very strict, there is a general possibility. If the X difference is large, it can not be universal, there will be the top of the tooth repair margin is too small phenomenon. Even when x=0 is rolling with the same knife, the average number of rolls is less, and the gears are smaller at the time of repair, while the number of teeth rolled seems larger.

Q:Hobbing machine hob installation angle is wrong, what will happen?Go to work in the middle of the hob stopped, and then use the manual to hob vertical movement, and then start the workpiece and why card and the card hob is bad? And the consequences?

For the share, I'll tell you. The angle is shifted, the hob's pitch is wrong. The back angle is also easy to take off.. If you move back, you'll certainly get stuck. With hob is also a certain relationship. Wenling Kaiyuan tool factory this kind of strength brand hob generally won't card bad. Don't forget to give me a bonus!!!!

The accuracy of the drawing gear determines the hob grade, which is basically the same as the national standard. You can also see the West Germany 5480 standards.

Q:Hobbing machine hob shaft strange ring, what's the matter?

The gear grinder is out of order and the gap is a bit too big

Q:What is the "hob" knife?

Hob: common knife, generally used for cutting brittle materials and the type of raw materials.From the end of the material into 45 degrees angle vertical vertical knife. Then turn the material to the body direction, according to the number of rotating material to determine the size of the dishes

Q:How to adjust the torque of disc hob commonly used in TBM?

Although this problem a long time ago, but still can answer, upstairs are not reliable. The torque of the disc hob is determined by adjusting the inside ring size. General choice of repair, after the experience is easy to handle, according to experience values often meet the requirements.

Q:The influence of hob accuracy grade on gear machining

It has something to do with smoothness! If shaving, the hobbing machine B will be enough! When we do not shave teeth, with double A knife shaving, then the series of knives will not affect too much

Q:What is the reason that the double gear hob changes the gear line of public gear too big?

The number of teeth of the theory is not suitable to duotou hob tooth number, use 9-11 double thread hob, usually duotou hob is to improve work efficiency, and processing precision will be relatively lower is certain, usually will be reflected in the pitch, what equipment you use, and your equipment speed of working table can handle?
